Topic: General

This talk applies lessons learnt from community health efforts during Covid-19 pandemic to open source software security. Just as you don’t need to be a medical professional to help protect yourself and loved ones from Covid, you don’t need to be a security engineer to help secure your open source community against rising attacks. We'll cover examples from security outreach efforts to address unique aspects of open source and will shareactionable ways and free tools to improve the supply-chain security of not only your own projects, but also the network of projects that depends on them.

Will Fancher
Topic: NixCon

When NixOS boots up, the first userspace code that the Linux kernel runs is called "stage 1". Its main job is to configure the file systems used by the OS before starting it. This can get quite complicated, and systemd is here to help.

I will describe the goals of rewriting stage 1 to use systemd. I will also talk about how these seemingly small choices, like how to handle the first few seconds of boot, or the choice of my online username, can have unexpectedly significant results.

Chris McKenzie
Audience: Everyone
Topic: General

There's a rich history of forgotten 1980s and early 1990s Unixes and ways of thinking about the home computer as workstation. Find out the history of both commercial and non-commercial efforts and how the Linux project successfully syncretized most of these strains to become the most popular Unix-variation. It might perhaps, give you new appreciations and ways of thinking about the systems and tools you use every day.

Audience: Intermediate

The IOCost cgroup controller implements hierarchical weighted block IO distribution based on model-calculated cost of each IO. This can be used to isolate IOs among applications and containers running on the same system. This presentation takes a look at how the IOCost controller works, how comprehensive memory and IO isolation can be achieved with it, and how the model parameters can be benchmarked using resctl-bench and distributed for out-of-the-box configuration.

Topic: Ubucon

Join us for an informative session on automating LLM fine-tuning and developing chat-based and multimodal model assistants.
